"An aftermarket chip for a stock configuration finds gains by tuning the ignition and fuel in areas where Porsche was conservative"
A major contradiction, where the emphasis was on STOCK!!!
Now who is to be believed?

I'm up for autopsy on this, as well,....Of course, I'm NO mechanic (I know the difference, however). I've certainly read about partial throttle response improvement with Wong's chip (and others) but would want to know "how" this is obtained (fuel amps or ignition maps,..other: BOTH).
For the patient instuctive types: what is changed within the maps when one simply removes the cat/converter and allows the engine to "breathe"....? And, to what degree?
I have to agree with Loren (thus far), as these "do" seem to contradict,..I mean, it IS what is,..what, in fact, is it?
Surely, there's an answer,..a clear one....
Of course, I'm the dumb-arse who never knew (rather, noticed) that my (89) baby was loaded with an Auto-Authority chip (for almost 1 1/2 years of ownership!) .....requiring nothing less than 92 octane gas (which, of course, I always run non-ethanol 93 octane from day one) .....I've not checked any of the parameters on this specific chip, thus far, but AM MOST interested to know more about it. Looking to put the Wong chip on board soon......I hope to get the part # to Steve so that he can read what's there (vs. how he does things)....I'm NEVER comfortable with changes (especially ignition advance) being unknown when the system DOES NOT have knock sensing and associated controls.
BEST!
